Hands-on with the Windows “Blue” desktop experience

The Beta fish is back in the new Windows “Blue” previews. This week, Microsoft is unveiling the previews for its Windows “Blue” operating systems—the Windows 8.1 client, Windows Server 2012 R2, and an update to Windows Server Essentials.  Last night, Microsoft released the previews through its MSDN and TechNet programs for its server platforms, which include a feature called “Desktop Experience”—an add-on which gives the server versions of the platform the same interface as Windows 8.1. As a result, Microsoft has tipped its hand about some of the interface changes it will be showing in the preview of the client, which it will release later this week. Here’s a quick look at the most significant changes in the interface we’ve found in our first hands-on with the preview revisions.   Read on Ars Technica | Comments

New Technique For Optical Storage Claims 1 Petabyte On a Single DVD

melios writes “Using a two-light-beam method a company claims to have overcome Abbe’s Law to dramatically increase the storage density for optical media, to the 9 nm scale. From the article: ‘The technique is also cost-effective and portable, as only conventional optical and laser elements are used, and allows for the development of optical data storage with long life and low energy consumption, which could be an ideal platform for a Big Data centre.'” Read more of this story at Slashdot.

DHS on border laptop searches: we can’t tell you why this is legal, and we won’t limit searches to reasonable suspicion

The DHS has responded to a Freedom of Information Act request filed by the ACLU asking when and how it decides whose laptop to search at the border. It explained its legal rationale for conducting these searches with a blank page: On Page 18 of the 52-page document under the section entitled “First Amendment,” several paragraphs are completely blacked out. They simply end with the sentence: “The laptop border searches in the [Immigration and Customs Enforcement] and [Customs and Border Protection] do not violate travelers’ First Amendment rights as defined by the courts.” More excellence from “the most transparent administration in American history.” Also, the DHS rejected claims that it should limit searches to situations where it had reasonable grounds for suspicion, because then they would have to explain their suspicion: First, commonplace decisions to search electronic devices might be opened to litigation challenging the reasons for the search. In addition to interfering with a carefully constructed border security system, the litigation could directly undermine national security by requiring the government to produce sensitive investigative and national security information to justify some of the most critical searches. Even a policy change entirely unenforceable by courts might be problematic; we have been presented with some noteworthy CBP and ICE success stories based on hard-to-articulate intuitions or hunches based on officer experience and judgment. Under a reasonable suspicion requirement, officers might hesitate to search an individual’s device without the presence of articulable factors capable of being formally defended, despite having an intuition or hunch based on experience that justified a search. Feds say they can search your laptop at the border but won’t say why [Cyrus Farivar/Ars Technica]

Sony Touts 25 Hour Battery Life For Haswell-Equipped Vaio Pro

An anonymous reader writes “Sony claims that both the new 11.6-inch and 13.3-inch models of its Haswell-equipped Vaio Pro ultrabooks are the world’s lightest. The 11.6-inch model weighs in at 1.9lb (0.87k , where as the 13.3-incher is a little heavier at just 2.33lb (1.06kg). But it’s the battery life on offer here that really makes the new Pros stand out. The 11.6-inch Vaio Pro offers 11 hours of battery life as standard, while the 13.3-inch achieves 8 hours. However, Sony is also offering a sheet battery you can connect to the base of the ultrabooks. On the 13.3-inch Pro that increases battery life to 18 hours, but on the 11.6-inch you get a true day-long amount of juice with 25 hours of battery life claimed.” Read more of this story at Slashdot.
